Abstract
Pervasive services and smart environments are becoming more and more popular as an ever‐increasing number of people enjoys these services typically by means of portable devices. These devices are battery‐fed and, thus, energy efficiency is a critical factor for the deployment of pervasive services. In this paper we focus on multimedia streaming services for mobile users. Specifically, we consider a scenario where mobile users with Wi‐Fi devices access the Internet to receive audio files from a remote streaming server. We propose a proxybased architecture and an energy‐efficient streaming protocol that minimize the energy consumption of the Wi‐Fi interface at the mobile device, while guaranteeing the real‐time constraints of the audio streaming. The experimental analysis performed on a prototype implementation shows that our solution allows an energy saving ranging from 76% to 91% of the total consumption due to the network interface. Moreover, it also preserves a good user‐level Quality of Service.

Abstract
Purpose
World imports of Italian sparkling wines fell by 9% in value and 5% in quantities. In view of this, the quality characterisation of these products is desirable to increase their market value and restore their global visibility.
Design/methodology/approach
For this purpose, in this paper, heavy metals (Cd, Co, Cr, Cu, Fe, Ga, Hf, Hg, Mn, Mo, Nb, Ni, Pb, Re, Sb, Sn, Ta, Th, Tl, U, W, V, Zn, Zr), rare Earth elements (REEs) (Ce, Dy, Er, Eu, Gd, Ho, La, Lu, Nd, Pr, Sm, Tb, Tm, Yb) and isotopes ratio (208Pb/206Pb, 207Pb/206Pb, 206Pb/204Pb, 208Pb/207Pb, 87Sr/86Sr) were analysed in Italian sparkling wines with Protected Designation of Origin (PDO) certification by High Resolution Inductively Coupled Plasma Mass Spectrometry (HR-ICP-MS) and MultiCollector Inductively Coupled Plasma Mass Spectrometer (MC-ICP-MS). The samples were produced in the Veneto region, and they were compared to white and red wines from the same area.
Findings
Sparkling wines present a characteristic elemental pattern compared to white and red ones, with lower content of heavy metals and higher content in REEs. The ratio 87Sr/86Sr resulted in a powerful micro-scale geographical origins marker while Pb ratios as winemaking process one, both useful to prevent possible frauds. Multivariate data analyses, such as PCA and PLS-DA, were used to develop a model of recognition of Venetian sparkling wines.
Originality/value
The good classification of sparkling wines was achieved (95%), proving the suitable use of these analytes as markers for recognising sparkling wines and their geographical origin verification. To the best of the authors’ knowledge, this is the first study investigating heavy metals, REEs and isotopes in Venetian sparkling wine for their recognition.

Abstract
Cryptoassets have recently attracted the attention of national and international financial regulators. Since the mid-2010s blockchains have increasingly been adapted to automate and replace many aspects of financial intermediation, and by 2015 Ethereum had created the smart contract language that underpins the digitization of real assets as asset-backed tokens (ABTs). Those were initially issued by FinTech companies, but more recently banks active on international capital and financial markets, and even central banks, for example, the Bank of Thailand, have developed their own digital platforms and blockchains. A wide variety of real and financial assets underpins ABTs, viz., real-estate, art, corporate and sovereign bonds, and equity. Consequently, owing to the significant market capitalization of cryptocurrencies, the Basel Committee on Banking Supervision (BCBS) published two consultative papers delineating its approach on cryptoasset regulation. In this study, the authors analyze the mechanics of ABTs and their potential risks, relying on case studies of recent issuance of tokens in equity, real-estate, and debt markets, to highlight their main characteristics. The authors also investigate the consequences of the increasingly oligopolistic structure of blockchain mining pools and Bitcoin exchanges for the integrity and security of unregulated distributed ledgers. Finally, the authors analyze the BCBS’ regulatory proposals, and discuss the reaction of international financial institutions and cryptocurrency interest groups. The main findings are, firstly, that most ABTs are akin to asset-backed securities. Secondly, nearly all ABTs are “off-chain/on-chain,” that is, the underlying is a traditional asset that exists off-chain and is subsequently digitized. The main exception is the World Bank’s bond-i that is genuinely native to the blockchain created by the Commonwealth Bank of Australia, and has no existence outside it. Thirdly, all ABTs are issued on permissioned blockchains, where anti-money laundering/anti-terrorist funding and know-your-customer regulations are enforced. From a prudential regulatory perspective, ABTs do not appear to pose serious systemic risks to international financial markets. This may account for the often negative reactions of banks, banking associations, and cryptocurrency interest groups to the BCBS’ 2021 proposals for risk-weighted capital provisions for cryptoassets, which are viewed as excessive. Finally, we found that issuance of ABTS and other smart contracts on permissionless blockchains such as Bitcoin and Ethereum could potentially generate financial instability. A precedent involving Ethereum and The DAO in 2016 shows that (i) there is a significant accountability gap in permissionless blockchains, and (ii) the core developers of blockchains and smart contract technology, and Bitcoin mining pools, exercise an unexpectedly high- and completely unregulated-amount of power in what is supposedly a decentralized network.

Abstract
Purpose
This paper analyzes the importance given by venture capital (VC) firms to the different characteristics of the patent portfolio of a young innovative company (YIC). In an attempt to go beyond previous studies, the authors argue that not only is the size of a technological portfolio significant but also its nature. It is also examined whether the correlation between patents and VC financing varies across different industrial sectors and over different rounds of VC investments.
Design/methodology/approach
The empirical analysis has focused on a sample of 1,096 European YICs between the years 2010 and 2014. Target companies were identified in the monthly bulletins of Go4Venture, which reported the largest European deals and gathered information on the amount of VC financing. Additional data was derived from FinSMEs and crunchbase. Industrial sectors were differentiated according to their ability to appropriate the returns of innovation by relying on patent protection mechanisms. A multivariate regression framework at the patent family level was adopted to investigate empirical associations between the amount of VC financing and the characteristics of a YIC's patent portfolio.
Findings
The results confirm the positive value of patents. Both the size and the characteristics of a YIC patent portfolio have been found to be positively associated with the total amount of VC financing. Additionally, the correlation between a YIC patent portfolio and VC investment varies across industries and over rounds of funding. Although the number of patents is positively correlated with VC investments in sectors with strong Intellectual Property (IP) regimes, the same does not apply to sectors characterized by lower patent intensity, where qualitative metrics seem to have a stronger correlation. Significant differences have also been found for the different rounds of VC investments.
Research limitations/implications
The limitations of this paper are related to data availability. Empirical associations have been investigated, but causal effects cannot be ascertained in this framework. The authors focused on a sample of firms that received VC funding. Several transactions were excluded, due to a lack of specifications pertaining to the round series. Furthermore, a number of potential drivers of the financed amounts, such as variables related to the founder or the management team, have not been considered in this study.
Practical implications
For firms operating in sectors with weak IP regimes, patents are positively associated with attracting equity capital, if they are the output of R&D collaborations and have higher technical merit. In industries where patent intensity is higher, patent portfolio size matters more than quality. This suggests that VC investors award innovation quality to cases in which patenting is less frequent. Since the results indicate that positive associations between patenting and VC financing are more significant in later stages, managers should plan their patenting strategy in advance to reap the related benefits, and then collect the premium at later VC stages.
Originality/value
In this paper, the importance given by VC firms to different characteristics of a YIC patent portfolio has been analyzed in terms of size, quality, and complexity. While previous empirical analyses mainly focused on a single sector, the authors have examined whether the relevance of patents for VC financing decisions varies across industries and over different rounds of investment. The geographical coverage of the sample is another novelty of the paper. Previous works focused on a limited number of countries, whereas this research has considered firms operating in several European countries.

Abstract
The importance of organizational-stakeholder relationships has been an interesting subject in the organizational literature.
In this chapter, the evolution of the concept of stakeholder and how crucial is the company’s interaction and cooperation with them to achieve common goals has been studied. Initially stakeholder was considered a synonym of shareholder but throughout the years the category has expanded including managers, employees, suppliers, and other key actors, until the current meaning: stakeholder is “any group or individuals who can affect or is affected by the achievement of the organization’s objectives” (Freeman, 1994). Hence for running successful businesses, the companies need to acknowledge the existing stakeholders and provide them expected benefits, proportionally to their relevance, which is based on their power, legitimacy, and urgency. The chapter concludes by showing us the main principles that identify the management duties to all stakeholders and the necessity of increasing their involvement in decision-making processes.

Abstract
Quality function deployment (QFD) is a method developed in Japan to help transform the voice of the customer into product characteristics and to control quality in the development/production phases. It minimizes the risk that products or services are far from the costumers’ needs and promotes company integration and quality management. Starting with the description of the “House of Quality,” the chapter explains how to build a QFD. Strengths and weaknesses of the methodology are also presented to the reader.

Abstract
This chapter aims at presenting the ISO 9000 standards and their crucial role in the regulation of the quality management process in a company. To achieve this goal not only have the standards been deeply scrutinized but also evidences of their importance and consequences of their application have been collected after a deep period of study and research.
The chapter begins with a quick review of the standards history, followed by a consistent part that describes the process of standardization and who releases the certifications. The following part is devoted to the analysis of the structure of the standards and the principles in which their content is based. The chapter ends highlighting the areas influenced by the quality standards and the benefits that they bring to the companies.
In conlusion, this section of the book is dedicated to a normative topic that is in continuous evolution and that influences a lot the quality management system.

Abstract
Purpose
This paper aims to know the dimension and scope that research on the district effect has had in the literature about industrial districts, as well as to shed some light on the connection between industrial districts and business results; or expressed differently, on how being located in an industrial district or not affects or might influence the performance of the firms located therein.
Design/methodology/approach
The purpose of this paper has been achieved through an exhaustive review of the empirical literature dedicated to the so-called district effect. The papers selected in the analysis were selected on the basis of the following criteria: (1) publications in scientific journals; (2) studies carried out in Spain and Italy; and (3) works published between 1994 and 2017.
Findings
The outcome of the literature review suggests, on the one hand, that the debate on the extent to which the territory influences the competitiveness of firms located in industrial districts still remains a topic of great interest. It can additionally be observed that most of the works dedicated to measuring the district effect have done so using three dimensions: (1) productivity/efficiency; (2) international competitiveness; and (3) innovation.
Practical implications
From a theoretical perspective, the findings of this paper make it possible to carry out an integrating proposal for the measurement of the district effect which revolves around three dimensions (productivity/efficiency; international competitiveness; and innovation).
Originality/value
This paper makes a twofold contribution to the literature: (i) it brings together the most important empirical contributions that measure the competitive advantages obtained by firms located in industrial districts through the district effect; and (ii) it theoretically and empirically establishes the essential dimensions of that effect.

Abstract
Six sigma is a structured methodology that uses mathematical and statistical tools to increase productivity and business efficiency. In order to apply it, it is necessary to have a very broad knowledge in the fields of mathematics, management, and sector to which the process or the product under consideration (mechanical, electronic, chemical, etc.) refers. It is based on guidelines with a rigid and formalized approach to deal with misunderstandings and minimize subjectivity as much as possible.
This chapter will provide the basic information regarding the birth of the methodology and the composition of the work team; moreover, the procedure define, measure, analyze, improve, and control (DMAIC) will be presented and some tools will be described in order to obtain the improvements desired for the product or the process.
